中文摘要：
为了解决矿井深部岩层水文地质条件的探测，论文探讨了接地线源短偏移距瞬变电磁法的理论及应用。论文介绍了基于感应涡流场电性源短偏移距瞬变电磁法的基本原理和工作方法，结合某煤矿深部采区岩层富水性探测，分析了测区地层的地球物理特征，在视电阻率和深度精细计算处理的基础上，详细分析了瞬变电磁法采用接地线源短偏移距装置进行大采深岩层富水性探测中的地质效果和可靠性，实现了采用1000m的短偏移距达到1500m的探测深度。研究表明，电性源短偏移距瞬变电磁法在探测深部采区岩层富水性方面具有探测深度大和地质效果好的特点。
英文摘要：
This paper studied the theory and application of transient electromagnetic method （TEM） with short-offset grounded wire source to detect the hydrogeological conditions in the deep strata. It introduced the basic principles and working method of TEM with short-offset grounded wire source based on induced eddy current field. Combined with an application of detecting strata water-bearing property of deep coal mining area in one coal mine, it analyzed the geophysical characteristics o{ exploration area, and the geological effects and reliability of TEM which use electrical source short-offset mode in detecting strata water-bearing property of deep coal mining according to apparent resistivity and depth fine data processing. This detecting reached 1500m in depth using short-offset of 1000m. The results showed that short-offset TEM can detect strata of greater depth and have better effects in detecting strata water-bearing property in deep coal mining area. Key words： transient electromagnetic method~ grounded wire source; shorboffset; strata water- bearing property; deep coal mining area
